August 2006 Challenge: Mathematical Concepts for Quilt Designing! (Page 2)

"Design a quilt that is an example of a math concept. You might like to do a search on the Internet for inspiration. Look for Diana Venters and Elaine Krajenke Ellison, who have written books about Mathematical Quilts: No Sewing Required. I'm sure you'll find some fun and very interesting things to design! If you're not very math oriented, ask your kids for some buzz words." - Barb Vlack

In 1974 Sol LeWitt composed "Straight Lines in Four Directions and All Their Possible Combinations", consisting of a grid of 15 squares, each inscribed with one or more horizontal, vertical, and diagonal lines in different orientations.

Barry Cipra, a mathematician, asked himself if it would be possible to rearrange 16 squares (one of them blank), without rotating any of the squares, so that all horizontal, vertical, of diagonal lines are unbroken within a 4x4 grid.

This is one of the three possible solutions, colored in the Angle Play fabric pallette.

A regular dodecahedron is one of the five Platonic solids, composed of twelve regular pentagonal faces, with three meeting at each vertex.

Use isosceles triangles (In an isosceles triangle at least two sides are of equal length.) to make little "mountains" on top of each pentagonal face, and you get a Small Stellated Dodecahedron.
The Small Stellated Dodecahedron is one of the four Kepler-Poinsot solids.

The width of the borders uses the fibonacci sequence.

I'm afraid maths isn't my strong point, so I kept it simple. It was easy to draft the mathematical symbols, - the rest of the blocks are from the EQ library.

Guildford, England

The shapes in this quilt remind me of the contents of my geometry set when I was at school. The block has been taken from a Kaffe Fassett book so it seemed appropriate to use his fabrics too.

The hypoteuses of these shells measure root 2, root 3, etc. Start with a right angle triangle with short sides of 1 and 1. The hypoteneuse will mearsure root 2. Build a right ang le triangle on that with the other short side of 1 and the new hypoteneuse is root 3. Continue adding triangle in this way and, if you have drawn accurately, you should be able to measure the square root of the n umbers used.

This quilt is based on a drawing by Escher - I love the way that you can't decide which way is up.I actually made it the hard way several years ago in my pre-EQ days. I had to use a scanned tracing which I enlarged on the computer and then sewed the shapes over paper, beforing applying them to the background fabric. In my quilt I used a large number of printed fabrics, but I used plains here to keep the files size down, but have kept the colours close to my original.

I had this concept buzzing around in my head before this challenge was suggested, so it begged to be presented here!

Thanks to Carol Baldry for the reminder of this game I used to play on my old computer. It makes a pretty quilt!

The block to create this quilt uses equilaterial triangles and trapezoids. The design changes depending on the colour you use for each patch.

Each block is a Tangram pattern. It has 2 large, 1 medium and 2 small triangles, one square and one parallogram.

One could cut this pattern (block) apart and make "things" with it like animals, boats, birds ect with the 7 pieces only.

The block sizes are based on the numbers in the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13, 21, 34). The borders widths are also the first 4 numbers of the sequence.

The block design is based on the star dahlia from the EQ5 block library.

Adelaide, South Australia

I started with the idea of those wooden counting blocks we used in early primary school (in units of 1-10). Then I saw that they could almost make a picture. In the end I came up with a simple illustration of symmetry from the blocks. Okay, so it's loosely mathematical!

The star block is designed with Fibonacci proportions; best done in 11 inch blocks. I drew this in March, 2006 when our local club set a project for each of us to do a Christmas themed quilt, so hence the Christmas theme. The applique borders are modified from the EQ library, as are the candles.
This one is about halfway sewn at this point!

Hilo, Hawaii

 

The blocks represent square roots.

The Center = 16 patch
Square Root of 16 = 4-patch blocks
Square Root = 2 patch blocks
Then: Bottom Corner = 9 patch
Square Root of 9 = 3
(Primary Colors)

Each multiple block is the colors
multiplied together
(2 patch = red & blue makes purple)
(9 patch = red + yellow & yellow + blue)

Philadelphia, PA

This quilt is fabric coloration of the Euler Square. Also called a Latin Square which is an array of numbers 1 to n - ie 00-99.
No row or column consists of the same number set. This quilt has ten rows and columns. The color arrangements depict the number sets.

Suduko puzzles are based on this theory.

This is an adaptation of the Fleur de Vie.
One of the beautiful arrangements of circles found at the Temple of Osiris at Abydos, Egypt (Rawles 1997). The pattern also appears in Phoenician art from the 9th century BC (Wolfram 2002, pp. 43 and 873). The circles are placed with six-fold symmetry, forming a mesmerizing pattern of circles and lenses.
This is a Reuleaux triangle theory noted by Wolfram.

Just like in the game, each fabric appears once per horizontal & vertical row, and only once in each of the 9 grids of 9.

(This gave me a chance to use 9 of my favorite floral fabrics from a STASH shopping bag))

Philadelphia, PA

This quilt incorporates the Fibonacci series numbers--1, 1, 2, 3, 5, 8, 13. The flower has 13 petals and the other shapes combine for the other numbers in the series.

Nacogdoches, Texas

Quilt was designed using the Fibonacci numbers (1,1,2,3,5,.....). I do have a copyright on the design, but it can be shared by participants in the August, 2006 challenge for personal use.
